Every time I see these stories, I'm reminded of the two guys in the southern US [NM or AZ IIRC] who couldn't pull the handle...[early system issue, since resolved] So they just glided the plane down for a landing. They had to get a mechanic out to fix whatever was wrong, then flew it out of the 'off-airport' site. So instead of destroying the a/c [which is always the case w/ these chute deployments] they handled the emergency like trained pilots and the result was LESS damage to the aircraft and people inside than if they'd been able to deploy the chute.
If you pull the chute, you destroy the a/c and you run the risk of lower back injury because the landing is like a 22ft free-fall to the ground. The seats don't give enough cushion and the lower back gets compressed etc.. while you may 'walk away' from the crash, you may not.. [it most certainly is an uncontrolled crash at that point]
I think these systems are a great idea but waaaaayy over utilized for incidents that they shoul

In reality there are body scanners in Canada, had one here just a couple weeks ago.. I requested a patdown but only by a female officer... got a funny look from that one then a flat out refusal. hrmm.... Body scanner it is then..
